What Is a Gas Detector?
- A gas detector is a device that can identify the presence of a wide array of gases within a given area
- Their most common uses are to detect gases which may be harmful for humans to breathe, and to detect gases which are flammable or otherwise dangerous
- They can be used across several different industries and are commonly seen in everyday use
Methods of Gas Detection:
- The method of gas detection depends upon the model of gas detector being used. Most detectors use either catalytic sensors or infared sensors
- Regular gas detectors need to be placed as near to the source of gas as possible to achieve an accurate reading. For these devices to work, it is required that the gas pass by the sensors for gas detection to occur. Ultrasonic gas detectors rely on specially tuned microphones which can detect the hiss of a gas leak. Most gas detectors are specially made or calibrated to detect only one specific type of gas. Modern gas detectors often have sensors to detect the presence of a particular gas and also use the aforementioned ultrasonic technology to detect gas leaks
- The majority of gas detectors are powered by battery so it is essential that the user makes sure to test the batteries in the device before proceeding to the test site. Some gas detectors have a backup set of batteries that can be installed and many are also chargeable via a power supply which can be plugged into a wall outlet
Package Included:
- 1 x Microprocessor Control Flammable Gas Detector
